The National Security Administration released a report on a decade’s worth of privacy violations — on Christmas Eve.

The agency posted the report to comply with a Freedom of Information Act request by the American Civil Liberties Union. It includes redacted reports to the president’s Intelligence Oversight Board from the fourth quarter of 2001, when surveillance increased because of the Sept. 11 terrorist attacks, to the second quarter of 2013.

The breaches include deliberate misuse of NSA surveillance capabilities by staffers who wanted to spy on spouses or lovers. But the agency said most violations of privacy were the result of unintentional mistakes.
